Bron: The Slotemaker History.
The following information about descendants of Aagje Keppel Slotemaker comes from Aagje's great grandson, Terry Slotemaker, who visited Holland and Noord Sharwoude in 1983. As far as is known, Terry is the first Slotemaker to return to Noord Sharwoude since Cornelis, Aagje, Anna and John came to America in 1883, a century before Terry's return.
"Two Keppel brothers from Noord Scharwoude married Jewish sisters from Amsterdam. Anna Keppel Roodenburg lived in Noord Scharwoude where the monument is located.  Relatives of Anna and Clara Keppel Roodenburg tried to hide them in a shed where seed potatoes were stored but someone reported them to the Nazi's. They were arrested, sent to Poland where they were gassed in Auschwitz on 6-March-1944. Anna's daughter Elly stayed with the v.Seventer family during that time. Gerda remembers her aunt very well, and Elly.
Mrs. v.Seventer is a Keppel. She visited us in America. Gerda is Mrs. Gerda v.Seventer Blokker, her daughter who now lives in Kalowna, British Columbia.
The caption at the top of the memorial is: Door(For) de(the) oorlog(war) gevallen(fallen) inwoners(inhabitants) van(from) Langedijk.
Langedijk consists of four villages in a row united, one being Noord Scharwoude.
Niesje Keppel hid a Jewish family in the attic of her boathouse during WWII. During that time she told no one except a farmer who brought them food. Her boathouse was next to her house along the canal. When the Canadian army liberated the village the Jewish family emerged ALIVE! Then the people of the village knew and celebrated.
Grietje Keppel Ijff who we visited in Holland in 1983 is a cousin to Mrs. v.Seventer and Niesje Keppel who is told about in the above story. ".
